The Effectiveness of Red Light Cameras In Washington and Oregon PublicDeposited

Descriptions

This study considered collision data for Seattle, Washington and Portland, Oregon
in order to determine whether or not red light cameras are effective in reducing red light
running collisions. Red light running is extremely dangerous and is a leading cause of
urban automobile collisions in the United States. Red light cameras have emerged as a
potential means to reduce the incidence of red light running, but their use is clouded in
controversy regarding effectiveness. There are two sides to the issue and any data can be
viewed from either standpoint, depending on the beliefs of the individual. This has
greatly complicated the interpretation of current studies on the issue and added to the
controversy.
The results from the analysis of the data from Seattle and Portland were
ultimately inconclusive. Both cities have very small amounts of collision data, making it
difficult to draw conclusions with any certainty. The data does, however, show a general
decrease in severe (angle) collisions, but the accuracy of this statement is unknown. In
addition, the definition of effectiveness and location also play a role in the difficulty of
interpreting the results.
